Answer: C)
Step-by-step explanation:
Since, the graph of an inverse trigonometric function will pass through the point ,
If this point satisfies the function,
For the function
If x = 1
Thus, is not satisfying function
,
⇒ The graph of is not passing through the point
For the function
If x = 1
Thus, is not satisfying function
,
⇒ The graph of is not passing through the point
For the function
If x = 1
Thus, is satisfying function
,
⇒ The graph of is passing through the point
.
For the function
